Wow, there are lots of different lifts out there. Can someone list the better models available today? I would like to know how much clearance is required and whether or not they hide away or not.
Thanks

My preference would be for simplicity and minimal mechanical application.
Cover Butler is a frame that the cover will "hang" on that can be attached to the base or bottom of the spa, preferred mounting would be screwed to the deck if you are on a deck. 4-5 years from now when the cover increases it's weight from moisture, stress is applied to cabinet mounting aplications.
Cover mate is a frame that the cover will "hang on" that is attaached to the sde of the spa allowing a pivot point at the back, top of spa.
Both covers will obstruct view on the backside of the spa. This often is considered a privacy barrier or wind shield.
Hydraulic lifters are used when the cover does not have clearance behind the spa, but someone is going to break a hydraulic lifter possibly in the future.
Different lifter have different applications and you particular situation needs to be considered.
